CHARLES E. OANDEE, OF NEW YORK, N. Y.

CAR-AXLE BOX.

SPECIFICATION forming part-of Letters Patent No. 253,582, dated February 14, 1882.

Application filed December 19, 1881.

To all whom it may concern:

Be it known that 1, CHARLES E. GANDEE, of the city, county, and State of New York, have invented certain new and useful Improvements in Oar-Axle Boxes and Journal-Bearings, of which the following is a full, clear, and exact description.

My improvements relate to car-axle boxes containing anti-friction rollers for the journals of the axles; and the present invention is an improvement upon the devices shown in Letters Patent No. 233,068, granted to me October 12,1880.

My invention consists, first, in the devices for insuring continuous lubrication, and, secnd, in packing devices that render the box air and dust tight, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side view of an axle-box containing my improvements and with the back plate removed. Fig. 2 is a vertical transverse section of the box. Fig. 3 is a horizontal section on line 00 x of Fig. 1. Fig. 4 is a vertical longitudinal section on line 3 y of Fig. 3, and Fig. 5 is a cross-section of the packing-gland.

A is the axle-box, having its bottom portion, a, formed as a basin to contain the lubricant. The box is closed on all sides, the front by a plate, b, and the back by a plate, 0, all the joints being packed to exclude dust. The box is divided by a partition, d, to form two chambers, B B, the former and larger one, B, to contain the anti-friction rollers and journal of the axle, and the smaller chamber, B, to contain the lubricating devices. The chamber B is accessible by removal of front plate, b, and the two chambers connect by an opening, d, in the partition, so that the lubricating material shall be at the same level in both and pass freely from one to the other,

C is the axle, extending through a stuffingbox, D, in the back plate, 0, and through the chamber B and partition (I.

ter of the axle, so that the axle is centered between the rollers. The rollers are loose upon spindles c, f, and g, respectively. The spindles have bearings in the front of box A and abut against the plate I), and the rear plate, 0,

ends of the spindles. In the back plate are set screws 1, taking against the ends of the spindles, for use in setting them up tightly.

The opening in the stuffingbox D for the axle is eccentric, so that the axle bears on the box only at the lower side of the opening, as seen most clearly in Fig. 4. The opening in partition d is also eccentric, to prevent contact of the shoulderc' on the axle with the partition, except at the lower side. The box D contains suitable packing, that is surrounded by alapped circular band, k, of flexible or spring metal, (shown in Fig. 5 most clearly;) and the gland lof the box is provided with set-screws n, taking upon the band It, so that the bandcan be compressed and the packing made as tight as necessary. With these packing devices the box can be made dust and oil tight.

The lubricating devices are as follows: The hub of the upper friction-roller, c,-is formed to project over the oil-chamber B, and the projecting portion is made as a toothed wheel, m. In the oil-chamber is a flanged disk or Wheel, 0, sustained on'a stud, 19, that projects from front plate, I); and around the Wheelsm o is a chain, q, provided with buckets or knobs r. The chain being moved by the revolution of friction-roller c, the buckets carry the oil up from the chamber B to the roller. This insures a continuous supply of lubricant to the bearings of the roller.

It will be seen that the construction shown provides for the convenient access to and removal of the anti-friction rollers and other parts contained in the box. The rollers steady the journal and prevent any lateral or oscillating movement; The box being air-tight, dust cannot enter nor oi'l escape.

I prefer to place at each side of the packing beveled washers 24, (shown in Fig. 2,) which cover the openings in the box and gland and prevent the packing from entering.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent.

is formed with recesses h, that receive the rear 1. The anti-friction roller 0, provided with toothed wheel m, the loose wheel 0, fitted in the oil-compartment, and the chain or band q, substantially as shown and described,in combination with the box A, for operation as specified.

2. The combination, with the box A and the axle O, of the friction-rollers cfg, placed loosely upon the spindles ef g, having hearings in the front and rear plates of the said box, and the set-screws t, substantially as and for the purpose set forth.

3. The combination, With the box A, provided with partition (I, and the axle 0, provided with the shoulder i, of the stuffing-box D, the lapped circular flexible metal band k, the gland I, and 15 the set-screw at, substantially as and for the purpose set forth.

4. The anti-friction roller 0, provided at one end with a projecting gear-wheel, m, for receiv ing and giving motion to a lubricating chain or 20' band, substantially as -described.
